GAS WATER-HEATER.

Specification of Letters Patent.

Patented Nov. 21, 1916.

Application filed. May 3, 1915. Serial No. 25,426.

To all whom it may concern:

7 Be it known that I, GEORGE ALBER MOORE, a citizen of the UnitedStates, and resident of Los Angeles, State of California, have inventedcertain new and useful Improvements in Gas ater-Heaters, of which thefollowing is a specification.

The subject of this invention is intended as a device to be secured toan ordinary gas stove immediately adjacent to the burners thereof andpreferably arranged between the burners and the grid usually suppliedfor supporting a vessel to be heated by the burner.

The invention has for its principal object the providing of a meanswhereby water may be heated at the time and simultaneously with theheating of a pan or pot placed upon the gas stove, and I have soconstructed my device that it may be connected with a hot water tank orboiler of ordinary size and style and may operate satisfactorilytherewith 'even though the boiler or tank may have connected with itother means for heating the water contained therein.

My device may be arranged to operate as a single unit or as a pluralityof units though, if a plurality of units are used I prefer that theyshould be connected in multiple so as to reduce the radiating surfacewhich might tend to cool the water.

The following is what I consider the best means of carrying out thisinvention, and the accompanying drawings form a part of thisspecification in which Figure 1 is a large plan view showing a singleunit. Fig. 2 is a side elevation partly in section, and shows the unitset forth in plan in Fig. 1.

Similar reference numerals indicate like parts in all the figures wherethey. appear.

At 1, I have indicated the burner of a gas stove. This burner may be ofany shape or size as I desire it understood that my device may operatewith any of the well known type of burners. Should it be necessaryhowever to change the shape or size of my device I do not believe thatsuch changes will modify its functions of operating efficiency.Surrounding the burner though arranged upon a plan above that of theburner is the grid which consists of the ring 2, having a plurality ofinwardly projecting fine rs designed to Supp rt a ve el to be b atedabove the burner. These fingers which are indicated at 3, may be of anynumber.

The heater proper consists of a tubular member bent to form a number ofinwardly projecting loops as indicated at 4: one of which is arrangedadjacent to and partly surround each of the fingers 3, and a straightportion 5 extending between the bases of the fingers, the inwardprojections i and straight portions 5 together form a continuous memberbut it is obvious that it would not be desirable to continue this memherfor the complete circuit of the burner, I have therefore opened the,complete circuit, for the purpose of entering therein a water deliverypipe 6 and a hot water outlet 7.

The coil as I may sometimes call it and which consists of theprojections 1 and por tions 5 is supported upon lugs 8, 9, 10, and 11formed or cast integral with or secured to certain of the fingers 8.These lugs may be in the shape of semi-cylindrical loops formingefficient cradles for the support of the coil.

From its construction it will be observed that my device may be attachedto an ordinary gas stove, it being only necessary to supply to the stovethe grid and coil together with the necessary water connection.

From the foregoing description the operation of my device will no doubtappear obvious. I desire, however, to call particular attention to theeconomy resulting from the use of my invention. It is well known that inthe use of the ordinary fiat burner the useful heat derived therefromconstitutes but a small percentage of the heat generated from the gasconsumed, and I have learned from experience that a water heater such asI have constructed may be employed without materially reducing theefficiency of the burner and in any way slowing down the heating of thereceptacle placed over the burner.

I desire that the heating coil or pipe utilized in my device should bespaced above the burner and below the surface of a receptacle resting onthe grid or fingers 3. In this way I obtain a circulation entirelyaround the tubes or coil, and the coil does not tend to restrict theflame, the heat of which is to be utilized in an ordinary manner.

- Modifications may be made within th scope of the appended claimswithout departing from the principle or sacrificing the advantages ofthis invention.

Having carefully and fully described my invention what'I claim anddesire to secure by Letters Patent is:

1. A gas water heater the combination with a burner and a grid havinginwardly projecting fingers, of a tubular member, portions of whichproject toward the center of said burner and partially surround saidfingers and means formed integral with said fingers for supporting saidtubular member 2. In a water heater the combination with a gas burner ofa grid having a plurality of fingers a lug formed integral with eachsaid finger and projecting at each side thereof, a tubular member bentto produce a portion extending approximately parallel to each saidfinger and another portion between each pair of said fingers, saidtubular member being adapted to be received upon said lugs to besupported thereby,

Signed at the city of New York, county and State of New York this 22 dayof April, 1915, in the presence of these two witnesses.
